TECHNICAL FIELD OF THE INVENTION

This invention relates, in general, to equipment utilized in conjunction with operations performed in subterranean wells and, in particular, to a sand control screen assembly having a mechanically attached screen jacket.

BACKGROUND OF THE INVENTION

Without limiting the scope of the present invention, its background will be described with reference to producing fluid from a hydrocarbon bearing subterranean formation, as an example.

Since the beginning of oil production from subsurface formations, the industry has been concerned with efficient control of the movement of unconsolidated formation particles, such as sand, into the wellbore. For example, such formation movement commonly occurs during production from completions in loose sandstone or following hydraulic fracture of a formation. Production of these materials causes numerous problems in the operation of oil, gas or water wells. These problems include plugged formations, tubing and subsurface flow lines, as well as erosion of casing, downhole equipment and surface equipment. These problems lead to high maintenance costs and unacceptable well downtime. Accordingly, numerous methods have been utilized to control the movement of these unconsolidated formation particles during the production of fluids.

For example, one or more sand control screen assemblies are commonly included in the completion string to control the movement of formation particles. Such sand control screen assemblies are commonly constructed by installing one or more screen jackets on a perforated base pipe. The screen jackets may include one or more drainage layers, one or more screen elements such as a wire wrapped screen or single or multi layer wire mesh screen and a perforated outer shroud. Conventionally, screen jackets have been secured to the base pipe by welding.

It has been found, however, that the process of welding a screen jacket to a base pipe is sometimes very difficult due to the difference in metallurgy of the components. For example, the material used for the base pipe may be 13 chrome while the material used for the screen jacket may be a special alloy such as 304L stainless steel, 316L stainless steel, Inconel, Hastelloy or Monel. In addition, it has been found that welding a screen jacket to a base pipe typically requires a post weld stress relief process which can be time consuming. Further, it has been found that welding a screen jacket to a base pipe can cause damage to the screen jacket resulting in numerous types of failures in the sand control screen assemblies.

Accordingly, a need has arisen for an apparatus for attaching a screen jacket to a base pipe that does not require welding incompatibly different materials. A need has also arisen for such an apparatus for attaching a screen jacket to a base pipe that does not require a post weld stress relief process. Further, a need has arisen for such an apparatus for attaching a screen jacket to a base pipe that does not result in damage to the screen jacket.

SUMMARY OF THE INVENTION

The present invention disclosed herein comprises a sand control screen assembly for preventing the inflow of formation particles during production. The sand control screen assembly of the present invention does not require welding incompatibly different materials to connect a screen jacket to the base pipe. In addition, the sand control screen assembly of the present invention does not require a post weld stress relief process or result in damage to the screen jacket.

In one aspect, the present invention is directed to a sand control screen assembly for use in a subterranean well. The sand control screen assembly includes a base pipe having an outer surface and at least one opening in a side wall portion thereof. A screen jacket is disposed around the base pipe. The screen jacket has a filter medium and an outer shroud. The outer shroud has first and second ends with inner and outer surfaces. Connector rings form a mechanical interface between the base pipe and the first and second ends, respectively, of the outer shroud. Each of the connector rings is operable to mechanically induce permanent deformation in the outer surface of the base pipe and at least one of the inner surface and the outer surface of the outer shroud, thereby connecting the screen jacket to the base pipe.

In one embodiment, the connector rings prevent longitudinal movement of the screen jacket relative to the base pipe. In another embodiment, the connector rings prevent rotational movement of the screen jacket relative to the base pipe. In certain embodiments, each connector ring is disposed between the outer surface of the base pipe and an inner surface of the outer shroud. In other embodiments, each connector ring is disposed around the outer surface of the base pipe and an outer surface of the outer shroud. In one embodiment, the mechanically induced permanent deformation is achieved by crimping the connector rings to create penetrations into the base pipe and the outer shroud.

Preferably, the connector rings take the form of cylindrical rings having a cross sectional shape selected from the group consisting of a substantially rectangular shape, a substantially triangular shape and a substantially pyramidal shape. In some embodiments, the connector rings include spikes extending outwardly from an inner surface of the connector rings, an outer surface of the connector rings or both. In these embodiments the spikes may be removable inserts. In other embodiments, the connector rings include a plurality of friction riser extending outwardly from an inner surface of the connector rings, an outer surface of the connector rings or both.

Referring initially to FIG. 1, therein is depicted a well system including a plurality of sand control screen assemblies embodying principles of the present invention that is schematically illustrated and generally designated 10. In the illustrated embodiment, a wellbore 12 extends through the various earth strata. Wellbore 12 has a substantially vertical section 14, the upper portion of which has cemented therein a casing string 16. Wellbore 12 also has a substantially horizontal section 18 that extends through a hydrocarbon bearing subterranean formation 20. As illustrated, substantially horizontal section 18 of wellbore 12 is open hole.

Positioned within wellbore 12 and extending from the surface is a tubing string 22. Tubing string 22 provides a conduit for formation fluids to travel from formation 20 to the surface. At its lower end, tubing string 22 is coupled to a completion string that has been installed in wellbore 12 and divides the completion interval into various production intervals adjacent to formation 20. The completion string includes a plurality of sand control screen assemblies 24, each of which is positioned between a pair of packers 26 that provides a fluid seal between the completion string and wellbore 12, thereby defining the production intervals. Sand control screen assemblies 24 serve the primary function of filtering particulate matter out of the production fluid stream.

Even though FIG. 1 depicts sand control screen assemblies of the present invention in an open hole environment, it should be understood by those skilled in the art that the sand control screen assemblies of the present invention are equally well suited for use in cased wells. Also, even though FIG. 1 depicts one sand control screen assembly in each production interval, it should be understood by those skilled in the art that any number of sand control screen assemblies of the present invention may be deployed within a production interval without departing from the principles of the present invention. In addition, even though FIG. 1 depicts multiple production intervals separated by packers, it should be understood by those skilled in the art that the completion interval may have any number of production intervals including a single interval with a corresponding number of packers or no packers. Further, even though FIG. 1 depicts the sand control screen assemblies of the present invention in a horizontal section of the wellbore, it should be understood by those skilled in the art that the sand control screen assemblies of the present invention are equally well suited for use in wells having other directional configurations including vertical wells, deviated wellbores, slanted wells, multilateral well and the like. Accordingly, it should be understood by those skilled in the art that the use of directional terms such as above, below, upper, lower, upward, downward, left, right, uphole, downhole and the like are used in relation to the illustrative embodiments as they are depicted in the figures, the upward direction being toward the top of the corresponding figure and the downward direction being toward the bottom of the corresponding figure, the uphole direction being toward the surface of the well and the downhole direction being toward the toe of the well.
